Abstract
The utility model provides a T-shaped bolt, which comprises a bolt head, a polished rod body and a threaded body which are sequentially connected. A male thread is arranged on the side wall of the threaded body. The cross section of the bolt head is elliptic. The T-shaped bolt provided by the utility model has the advantages that since the cross section of the bolt head is elliptic and the edge of one side close to the polished rod body is rounded, the T-shaped bolt can be easily tightened by using a hand under the situation of no spanner and the round edge is not apt to injure the hand; and since the surface of the T-shaped bolt is plated with teflon, corrosion resistance is good, the T-shaped bolt is not apt to rust, the service life of the bolt is prolonged and the situation that the bolt is bonded with a nut due to corrosion is not caused.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of T type bolt.
Background technique
Bolt belongs to fastening piece, has bolt in each field substantially.Traditional bolt is made up of threaded body and head, and head is regular hexagon, must just can tighten by instruments such as spanners, be difficult under the situation of spanner tightening or unclamping lacking, very inconvenient, and traditional bolt is corroded easily, be bonded together thereby cause with nut, can't unclamp.
The model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model provides a kind of can manually tightening or unclamp, and the good T type bolt of anti-corrosion capacity.
(2) technological scheme
For solving the problems of the technologies described above, the utility model provides a kind of T type bolt, comprises the bolt head 1, polished rod body 2 and the threaded body 3 that connect successively, and described threaded body 3 sidewalls are provided with outside thread, and the cross section of described bolt head 1 is oval.
Further, the diameter of described polished rod body 2 is less than the diameter of described threaded body 3.
Further, the width b of described bolt head 1 is identical with the diameter of described polished rod body 2.
Further, described bolt head 1 is near a side margin rounding of described polished rod body 2.
Further, described threaded body 3 end edge chamferings.
Further, described T type bolt surface plating Teflon.
(3) beneficial effect
The utility model T type bolt, bolt head cross section are oval, and at the edge rounding near polished rod one side, hand-tight make-up under the situation of no spanner easily, and circular edge is difficult for hurting hand; Surface plating Teflon, so corrosion resistance and good are difficult for getting rusty, and have prolonged the working life of bolt, can not cause the situation that makes the bolts and nuts bonding because of corrosion.
Description of drawings
Fig. 1 is the utility model T type bolt arrangement schematic representation;
Fig. 2 is the left view of Fig. 1.
Embodiment
Consult Fig. 1 ~ Fig. 2, the utility model provides a kind of T type bolt, comprises the bolt head 1, polished rod body 2 and the threaded body 3 that connect successively, be provided with outside thread at threaded body 3 sidewalls, the cross section of bolt head 1 is oval, also can be described as runway shape, and it can tighten or unclamp with hand; In the utility model, the diameter of polished rod body 2 is less than the diameter of threaded body 3; The width b of bolt head 1 is identical with the diameter of polished rod body 2, and at the bolt head 1 side margin rounding near polished rod body 2, said structure makes can be not injured under hand-tight make-up or the situation of unclamping; In threaded body 3 end edge chamferings, this chamfering is more than or equal to 1.6mmX45 °; In order to improve its working life, not perishable, at T type bolt surface plating Teflon.
The utility model T type bolt, bolt head cross section are oval, and at the edge rounding near polished rod one side, hand-tight make-up under the situation of no spanner easily, and circular edge is difficult for hurting hand; Surface plating Teflon, so corrosion resistance and good are difficult for getting rusty, and have prolonged the working life of bolt, can not cause the situation that makes the bolts and nuts bonding because of corrosion.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
